Abstract
Wind turbine blade pitch control system including hydraulic actuators which pivotally drive the blades about the longitudinal axis thereof to adjust the blade pitch. The actuators are supplied with hydraulic fluid from independent sources thereof for normal blade pitch adjustment and feathering. Means are provided which, during feathering, isolate the pressurization and drain of the actuators from certain system components, whereby such pressurization and drain are not hampered by any malfunction of such components.
